Abstract

fetched live from OpenAlex

The ability to acclimate to a range of light regimes is important, given that shady understory habitats can receive only a fraction of the light available at the top of the canopy. Sun and shade leaves are known to differ in their set of biochemical and morphological characteristics. In recent years, much has also been learned about the effect of shade on xylem structure and function. Several studies found that shaded plants had narrower xylem conduits than plants growing in full sun. Among the most notable responses induced by shade is a shift of xylem vulnerability to cavitation. Shaded plants are typically more vulnerable to cavitation than plants exposed to full light. This appears to coincide with the construction of weaker intervessel and intertracheid pit membranes in shade. Before entering and after exiting the xylem, water moves through living cells in roots and leaves, respectively. This nonvascular pathway can be modified by aquaporins. Rapid changes in root and leaf hydraulic conductance in response to changes in light and transpirational demand have been described. The role of aquaporins in these responses is discussed.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
